Taall whom it may concern:

Be it known that 1, PAUL "WI LIA PICK, a citizen of the United States, residing at Portland, in the countyof Multnomah and State of Oregon, haveinvented certain new and useful Improvements in Sanitary Non- Spillable Milk-Buckets, of whichthe following is a specification.

This'invention relates to a sanitary nonspillable milk bucket and has for its objects,

first, the provision of novel means whereby foreign material will be prevented from having access to the bucket; novel means for preventing the milk from spilling, should the bucket be overturned or dropped; and a novel arrangement of top whichcan be readily applied ito or removed from the bucket andadapted and arranged for the convenient detachment of parts for the purposeof cleansing'them. 1

Another Object of the invention is 'the provision of an. improved "top for milk buckets having asform-adapting it to catch the spray from the milk as it is poured into the bucket and prevent the spray from'spattering outside the bucket.

A further object is the provision of a novel top for milk buckets comprising a concave bottom wall,a'n overhanging collar or part surmounting saidwall and serving as a spray retainer ordeflector, and a novel valve f detachably carried by the bottom wall and cooperating with a seat thereon, the said structure being a unitary'and selficontained arrangement which can be applied to or removed from the bucket. The valve isnormally open, premitting the free entry of milk 'into the bucket and allowinggthe milk to be poured from the bucket through the usual spout, but said valve is so arranged and adapted that should thebucket be dropped or tipped, thepressure of the milk against the valve will cause the latter to close against the seat and prevent the milk from spilling;

The opening provided with a gauze strainer which prevents hairs, dirt andforeign material from entering the bucket. f

Another object of the invention is the provision of an attachable and removable supplemental strainer which may be, applied to the upper part of the cover to initially, strain the milk before it passes withinthe The invention is susceptible of 'modificathrough the valve seat is.

The upper edge of the bucket 1 is bent H around a circular reinforcing band "9 as shown at 10; this strengthens and renders ri 'id the mouth of the bucket so that the 1 1 cover can fit snugly thereon.

My improved cover 1s sh'own generall'y at 11 and it is provided with a'flared mouth 12 through which the "milk may readily pass.

Below the mouth '12 is the 'overhanglng, preferably convex, portion 13 which has a' concave or funnel shaped bottom 14;; I'do not, limit the part 18 to: the precise form shown as vari'ations may'fberesorted to. A

flange 15 depends fr'ornthe cover andiszi ly adapted to fitsnugly around thejmouth of. the bucket 1. The concave or funnel shaped bottom 14: causes the milk to drain through the center thereof whereit passes into the bucket through the tapered valve seat 16.

The valve seat is provided with a gauze strainer 1.7. Surmounting the bottom l4 and supported above the gauze strainer 17 is a tube 18 which is held by braces 19.

- The valve 20is of concavo-convex circu lar form and is provided with a tapered valve plug 21 which is adapted to fit inthe tapered seat 16 when the valve is in" raised position, thereby "closing communication between the space abovethebottom l4: and the interior of the bucket. The valve is provided with astem 22 which has an L-shaped slot 23 in itsupper end and said stem fits inside the tube 18 and is adapted toslide up and down therein. V .l

A collar 24c'fitting over the end of the stem 22, is provided with a pin 25 which is re ceivedin the slot 23. .The collar 24 rests upon the upper end of the tube 18 and holds the valve in the suspended-position shown in Fig; 2; giving the collar'24 a turn, it

can be: detached from the stem 22 whereupon the valve may be removed, thus enabling thorough cleansing of the parts to be obtained. a I r 7 Normally the parts are in the position shown in Fig. 2, the valve then being open.

V The milk entering through the mouth 12,

' strikes the bottom 14 and passes through the strainer 17 onto the upper sloping face of the valve 20. The plug 21 is circular in form and so is the valve loody20. Consequently, the

milk passing down through the valve seat 16 readily drains ofitheperiphery of the' valve '20 and:falls into the bucket. If, however, the bucket isdropped or tilted over onits side, the milk in the buck et strikes against the valve 20 and closesit, the valve plug 21 then entering the seat 16 and cutting ofli communication between the interior of the bucket and the insideof the cover 11; consequently, it is impossible to spill the contents of the bucket. The spout 2 being closed by the cover 6,fthe milk cannot pass out throughv the spout when the bucket is dropped or tilted. p

' The form of the part 13: insures that milk spattering. up from the bottom 14: will strike .against said part 13 and be deflected back onto'the bottom instead of spattering out of the mouth of the bucket. 1 ,Theentire cover, together with the valv as shown in Fig. 2,can be removed from the bucket as a unit'and' cleansed or the valve valve may takenout. Similarly, the said :cover and be applied as a unit to the bucket." Y F l *xAs it may beflfound of advantage to pre-.

liminarily strain the milk before it strikes the bottom 14, I provide the supplemental strainer shown in Figs. 4 and 6, comprising the guide to hold'the valve in a split springring 26 having hooks 27 to engage the cover where the parts12 and 13 join, as shown atf28. The ring has small hooks 29 which engage the gauze 30. The

entire ring can be quickly applied to the cover and, after milking has been completed,it may be removed and cleansed.

The cover '11 maybe detachably secured to the bucket in any preferred'way; a'bayonet joint 30 being'shown for-that purpose, but Without limitation toth-is particular fastening means.- I

WhatIclaim is: a 7 1. A cover for a milk bucket comprising an inclined or funnel shaped bottom wall,

bottom wall, a valve-seat atthe center of by'the cover, a valve having a stem slidable in the guide, and a removable collar con} nected to the stem and adapted to rest on position.

2. A cover for a milk bucket comprising an inclined or funnel shaped bottom wall, an overhanging -portion surmounting said bottom wall, a valve seatat the center of the bottom wall, a valve stem guide carried an overhanging portion surmounting said the bottomiwall, a valve stemguide carried 7Q suspended V slidable in said guide, a-removable'collar 7 connected to said stem and adapted to rest on the guide, and a valve for said seat, said valve having a facelof relatively great area located r insidefthe bucket in position to re? ceive the pressure of thef-milkwhen the bucket is dropped ortiltedforthe purpose ofcausing thevalve to close.
